Analysis of disease spectrum of hospitalized children during outbreak of coronavirus disease 2019 in pediatric department of a tertiary general hospital in Shanghai.

Objective To analyze the changes of disease spectrum in pediatric inpatients before and after the outbreak of coronavirus disease 2019 (COVID-19). Methods The data of gender, age, habitual residence, diagnosis and other relevant information of 1 931 hospitalized children in Department of Pediatrics, The First Affiliated Hospital of Naval Medical University (Second Military Medical University) from Feb. 2019 to Jan. 2020 (1 year before the COVID-19 epidemic) and 618 hospitalized children from Feb. 2020 to Jan. 2021 (1 year after the COVID-19 epidemic) were collected. The total number, habitual residence, gender and disease spectrum of hospitalized children 1 year before and 1 year after the COVID-19 epidemic were statistically analyzed. Results The number of hospitalized children decreased by 68.00% (1 313/1 931) 1 year after the COVID-19 epidemic. The number of hospitalized children from other provinces and cities was decreased (17.80%110/618vs 29.00%560/1 931) and there was significantly difference in the distribution of habitual residence of hospitalized children between 1 year before and 1 year after the COVID-19 epidemic (P<0.01). One year after the COVID-19 epidemic, the number of children with respiratory diseases decreased by 92.04% (971/1 055), and the proportion was also decreased (13.59%84/618vs 54.63%1 055/1 931);the number of children with endocrine system diseases increased by 20.71% (29/140), and the proportion was increased (27.35%169/618vs 7.25%140/1 931);the number of children with neonatal diseases decreased by 43.01% (166/386), but the proportion was increased (35.60%220/618 vs 19.99%386/1 931). Compared with 1 year before the COVID-19 epidemic, there were significant differences in the proportions of respiratory diseases, endocrine system diseases and neonatal diseases in hospitalized children 1 year after the COVID-19 epidemic (all P<0.01). The age distribution of hospitalized children 1 year before and 1 year after the epidemic of COVID-19 was different (P<0.01), and the number of hospitalized children was also different in different seasons (P<0.05). One year after the epidemic of COVID-19, the number of hospitalized children with respiratory diseases was decreased most significantly, and the number of children with pneumonia decreased by 93.71% (655/699), with a significant difference found in the proportions of pneumonia between 1 year before and 1 year after the COVID-19 epidemic (52.38%44/84vs 66.26% 699/1 055, P<0.05). Compared with 1 year before the COVID-19 epidemic, the proportion of endocrine system diseases such as short stature/growth retardation was decreased and the proportion of precocious puberty/early puberty development was increased 1 year after the COVID-19 epidemic (P<0.05). Conclusion The COVID-19 epidemic has led to a significant decrease in hospitalized children in department of pediatric, especially in the proportion of respiratory diseases, but it has led to an increase in hospitalized children with endocrine system diseases, suggesting that epidemic prevention and control measures can effectively reduce respiratory diseases requiring hospitalization, but may increase precocious puberty and early puberty development. These changes should be considered by department of pediatrics in general hospitals.Copyright © 2022, Second Military Medical University Press. All rights reserved.

Low-Dimensional Compounds Containing Bioactive Ligands. Part XX: Crystal Structures, Cytotoxic, Antimicrobial Activities and DNA/BSA Binding of Oligonuclear Zinc Complexes with Halogen Derivatives of 8-Hydroxyquinoline

Two tetranuclear [Zn4Cl2(ClQ)6]·2DMF (1) and [Zn4Cl2(ClQ)6(H2O)2]·4DMF (2), as well as three dinuclear [Zn2(ClQ)3(HClQ)3]I3 (3), [Zn2(dClQ)2(H2O)6(SO4)] (4) and [Zn2(dBrQ)2(H2O)6(SO4)] (5), complexes (HClQ = 5-chloro-8-hydroxyquinoline, HdClQ = 5,7-dichloro-8-hydroxyquinoline and HdBrQ = 5,7-dibromo-8-hydroxyquinoline) were prepared as possible anticancer or antimicrobial agents and characterized by IR spectroscopy, elemental analysis and single crystal X-ray structure analysis. The stability of the complexes in solution was verified by NMR spectroscopy. Antiproliferative activity and selectivity of the prepared complexes were studied using in vitro MTT assay against the HeLa, A549, MCF-7, MDA-MB-231, HCT116 and Caco-2 cancer cell lines and on the Cos-7 non-cancerous cell line. The most sensitive to the tested complexes was Caco-2 cell line. Among the tested complexes, complex 3 showed the highest cytotoxicity against all cell lines. Unfortunately, all complexes showed only poor selectivity to normal cells, except for complex 5, which showed a certain level of selectivity. Antibacterial potential was observed for complex 5 only. Moreover, the DNA/BSA binding potential of complexes 1–3 was investigated by UV-vis and fluorescence spectroscopic methods.

[Features of unintentional injury in children under the impact of coronavirus disease 2019]. / æ–°åž‹å† çŠ¶ç— æ¯’è‚ºç‚Žç–«æƒ ä¸‹å„¿ç«¥æ„å¤–ä¼¤å®³çš„ç‰¹å¾.

OBJECTIVES: To study the features of unintentional injury in children under the impact of coronavirus disease 2019 (COVID-19). METHODS: A retrospective analysis was performed on the medical data of 2 526 children with unintentional injury in Xinhua Hospital Affiliated to Shanghai Jiao Tong University School of Medicine from July 2019 to June 2022. The study period was divided into 5 stages: before the epidemic (July to December, 2019), the Wuhan epidemic period (January to April, 2020), the epidemic remission period in China (May 2020 to February 2022), the Shanghai epidemic period (March to May, 2022), and the epidemic remission period in Shanghai (June 2022). The incidences of unintentional injury in children at different time stages and different ages were compared. A questionnaire survey was conducted on 107 children of the 2 526 children to explore the features of unintentional injury. RESULTS: There were significant differences in gender composition, age, age distribution and proportion of many types of unintentional injuries among the five time stages (P<0.05). There was a reduction in the number of children who attended the emergency department due to unintentional injury during the Wuhan epidemic and the Shanghai epidemic. The proportion of children with trauma-related unintentional injuries in each stage reached more than 50%, and the proportion of children with trauma-related unintentional injuries reached 63.9% and 82.0%, respectively during the Wuhan epidemic and the Shanghai epidemic. Most children suffering from unintentional injury were mainly school-aged and preschool children (1 823 children, 72.17%). Compared with the same period of Shanghai epidemic in 2021, the age of children with unintentional injury was younger (median 7 years vs 11 years), and the proportion of children with trauma-related unintentional injuries increased (97% vs 69%) during the Shanghai epidemic (P<0.05). CONCLUSIONS: Under the COVID-19 epidemic, there is a reduction in the number of children with unintentional injury, while there is an increase in the proportion of children with trauma-related unintentional injuries. Unintentional injury is more common among school-aged and preschool children.

[Changes in the disease spectrum in the pediatric intensive care units within 2 years before and after the outbreak of coronavirus disease 2019]. / æ–°åž‹å† çŠ¶ç— æ¯’è‚ºç‚Žç–«æƒ å‰åŽ2å¹´å„¿ç«¥é‡ç—‡ç›‘æŠ¤ç— æˆ¿ç–¾ç— è°±çš„å˜åŒ–.

OBJECTIVES: To investigate the changes in the disease spectrum among hospitalized children in the pediatric intensive care units (PICU) within 2 years before and after the outbreak of coronavirus disease 2019 (COVID-19). METHODS: The related data on disease diagnosis were collected from all children who were hospitalized in the PICU of Affiliated Hospital of Jining Medical College from January 2018 to December 2019 (pre-COVID-19 group) and from January 2020 to December 2021 (post-COVID-19 group). A statistical analysis was performed for the disease spectrum of the two groups. RESULTS: There were 2 368 children in the pre-COVID-19 group and 1 653 children in the post-COVID-19 group. The number of children in the post-COVID-19 group was reduced by 30.19% compared with that in the pre-COVID-19 group. There was a significant difference in age composition between the two groups (P<0.05). The top 10 diseases in the pre-COVID-19 group by number of cases were respiratory diseases, neurological diseases, sepsis, critical illness, circulatory system diseases, severe neurosurgical diseases, digestive system diseases, unintentional injuries, endocrine system diseases, and tumors. The top 10 diseases in the post-COVID-19 group by number of cases were respiratory diseases, neurological diseases, sepsis, circulatory system diseases, unintentional injuries, endocrine system diseases, severe neurosurgical diseases, acute abdomen, trauma surgical diseases, and digestive system diseases. The proportions of respiratory diseases, critical illness and severe neurosurgical diseases in the post-COVID-19 group were lower than those in the pre-COVID-19 group (P<0.05), while the proportions of unintentional injuries, acute abdomen, endocrine system diseases, trauma surgical diseases and sepsis were higher than those in the pre-COVID-19 group (P<0.05). CONCLUSIONS: COVID-19 epidemic has led to a significant reduction in the number of children admitted to the PICU, and there are significant changes in the disease spectrum within 2 years before and after the outbreak of COVID-19. Relevant prevention and control measures taken during the COVID-19 epidemic can reduce the incidence of respiratory diseases, neurological diseases, and other critical illness in children, but it is necessary to strengthen the prevention of unintentional injuries and chronic disease management during the epidemic.

Impact of the COVID-19 Outbreak on Disease Spectrum of Pediatric Intensive Care Units.

Purpose: We aimed to analyze the changes in the disease spectrum data of a pediatric intensive care unit (PICU) in Nanjing, China, during the COVID-19 outbreak and explore a feasible plan for the treatment of critically ill children. Methods: This retrospective study used data from our PICU from 1 January 2018 to 31 December 2020. Patient demographics, distribution of disease spectrum, results of etiological examinations, and the PICU length of stay (LOS) were compared during the COVID-19 period (2020) and the previous years (2018 and 2019). Results: In 2020, the number of PICU admissions was 46.8 and 47.8% lower than that in 2018 and 2019, respectively. There were significant differences in the number of patients in PICU among different age groups, and these differences were mainly found in children aged <4 years and older than 14 years. The percentage of the number of patients in PICU with respiratory diseases decreased significantly, while those with hematological diseases, poisoning, and rare diseases increased significantly. Moreover, the number of patients with rare diseases increased significantly, while the number of patients with mitochondrial diseases exceeded that of those with autoimmune encephalitis. The PICU LOS in 2020 was higher than that observed in 2018 and 2019, indicating that the changes in the PICU disease spectrum did not directly affect the PICU LOS. Etiological examinations revealed that during the COVID-19 period, the number of patients in PICU with bacterial infections increased, and those with viral infections decreased, although not statistically significant. Conclusions: A striking decrease in the number of PICU admissions was observed during the COVID-19 outbreak, which caused a significant change in the PICU disease spectrum. Changes in the number and characteristics of patients admitted to PICUs should be considered for facilitating the effective working of PICUs during the COVID-19 pandemic.

Dynamic changes of emergency visits: a retrospective observational study.

BACKGROUND: With more emergency visits, there is increasing pressure to provide emergency medical services globally and locally. This study aimed to investigate the epidemiological characteristics and the disease spectrum of patients presenting in the last three years to the Department of Emergency Medicine of Tianjin Medical University General Hospital, a tertiary hospital in Tianjin, China, to improve the services of the emergency medicine department. METHODS: A retrospective study was conducted on all patients in the Department of Emergency Medicine of Tianjin Medical University General Hospital from Jan 1, 2017, 00:00:00 to Dec 31, 2020, 23:59:59, including variables like medical record number, gender, age, date of admission, principal diagnosis. The data were analyzed by SPSS statistical software; statistical charts were prepared by GraphPad Prism9.0 and SPSS 20.0; statistical tables were made by Microsoft Excel. RESULTS: A total of 1,314,916 patients presented to the Department of Emergency Medicine of Tianjin Medical University General Hospital from Jan 1, 2017, 00:00:00 to Dec 31, 2020, 23:59:59. In terms of gender distribution, the male-female ratio was 0.78∶1. As for age distribution, patients aged 60-69 were the most (23.47%), and patients younger than 20 years were the least (2.80%). Concerning monthly data, the number of visits peaked during January and December. The distribution of daily visits showed the feature of three highs and a low. The top three prevalence diseases in the emergency disease spectrum were respiratory, cardiovascular, and digestive diseases. The respiratory system was the most common in patients with infectious diseases (200,912, accounting for 86.97%). Among the patients suffering from infectious diseases, the number of patients with respiratory infections peaked in 2019 (73,530) and was the lowest in 2020 (20,078). CONCLUSIONS: From 2017 to 2019, the demand for emergency services in Tianjin Medical University General Hospital continued to increase, but it was greatly affected by COVID-19 in 2020. This emergency department is mainly for patients with respiratory system, circulatory system and digestive system diseases, and its treatment time is relatively centralized. The prevention of diseases for people of all ages, especially female patients and the elderly, should be strengthened, and emergency medical resources should be allocated reasonably according to the peak months and crowed periods of patients.
